我正在尝试使用rails中的PDFkit gem来生成特定div的pdf。我收到了这个错误：
incompatible character encodings: ASCII-8BIT and UTF-8
当我将其添加到我的视图中时会发生：
<%= render :text => PDFKit.new("<p>Hello World<p>".force_encoding("UTF-8")).to_pdf %>
我还将其添加到Application.html.erb
的头部<meta http-equiv="Content-type" content="text/html; charset=utf-8" />
我正在尝试对UTF-8强制执行编码。难道我做错了什么？有没有人找到解决方案？
Initializer（pdfkit.rb）：
PDFKit.configure do |config|
config.wkhtmltopdf = `which wkhtmltopdf`.to_s.strip
config.default_options = {
:encoding=>"UTF-8",
:page_size=>"A4",
:margin_top=>"0.25in",
:margin_right=>"1in",
:margin_bottom=>"0.25in",
:margin_left=>"1in",
:disable_smart_shrinking=>false
}
end
